Fig. XVI is an enlarged detail view of one of the exterior thread-forming diesel-nd coincident parts; Fig. XVII is a front elevationof the machineframe and driving mechanism. Fig. XVIII is a vertical cross-sectional lview taken on the' 6o line XVIII XVIII, Fig. XVII, showing the driving mechanism partly in elevation.

`l designates thetable of the machine, sup# ported upon the frame 2, (seel Figs. XVII and XVIIL) said frame vhavin-g a longitudinal cross-bar 3 and a transversely-extending cross-bar 4. Mounted in posts 5 is a crankshaft 6, provided with a driving-,pulley 7, to which a belt may be applied to impart rotation to the shaft. The crank-shaft receives 7o `the connection of one end of Aa link 8, pivotally connected at its opposite end to an arm 9' projecting from a toothed segment, 10 fixed to a stub-shaft 11, that is mounted in a jour; nal-box 12 on the cross-bar 4. The teeth of 75 the segment 10 engage the teeth of a pinion 13, fixed to adriven shaft 14, mounted in the frame 2.

" 15 is a grooved pulley rigidly mounted on `the shaft 14 and adapted to receive a driv- 8o ing-belt 16, by which movement is imparted rto the parts of the machine hereinafter to beV referred to. Surmounting the table 1 is asupplemental posts 1S, 20, 85 and 22, equipped at their upper ends with journal-bearings 19, 21, and 23. Mounted in the journal-bearings 19, 21, and 23 is a shaft 24., the rear end of which is equipped with a screw 25 and which intermediate of its ends 9o contains a groove 26. (See Fig. III.) The shaft turns in the journal-bushing 27 in the journalbea'ring 23, said bushing being provided with a sc,rew-threadedV neck 2S, to which reference will hereinafter be made. u 29 is a bevel-pinion loosely mounted on the shaft 24 and connected thereto by featheringscrews 32, seated in the hub-neck 30 ofthe pinion, thatenter the groove 26 in the shaft and permit of the shaft moving longitudinally roo through the pinion, while at the same time holding the pinion from turning on the shaft. The pinion 29 contains a groove 31, adapted to receive the driving-belt 16 to communicatebevel-gear 37 is arranged to receive the engagement of the teeth of the bevel-pinions 29 and 34, whereby movementis imparted to said bevel-gear from the turning of the pinion 34, and the pinion 34 turned in the reversedirection from the pinion 2,9,to revolve the sleeve 33 contrary to theshaft 24. The shaft 2 4` and the sleeve 33l are not intended to rotate contin-uously,'but are turned alternately first. in one direction and then in the other direction, 'each `part moving two revolutions in one. direction and then being reversed and movingtwointheother direction. This alternating movement is accomplished by the toothed segmentlOand pinion 13fand. driving parts connected therewith. The teeth of the segment arein multiple by two of the teeth inthe pinion 13, so. that when said segment isrock-ed by the crank-shaft 6 it turns the pinion 13 alternately forwardly and backward-ly.

3,8. designates a collar loosely mounted. on the sleeve 33forward of the post 18,'said collar being provided with a groove 39, adapted torece've a yoke 40, to which reference will subsequently be made. Projecting from the sleevej33 are ears 41, that receive the pivotal connection of levers 42, having rearwardlyextending arms,V 45, provided with slots 46,

(see Fig. IL) arranged to receive screws 47,

66y by a bolt 69. (see-Figs. I and II) and hav-' ing an open rear end. The. frame 68 is con-` structed with an eye portion 70,y rigid therethat enter the collar 38 to connect the arms and collar. The forward ends of the levers 4 2 are formed with arms 43, that upon their front.facesareprovided with dovetail tongues,

44. (See Fig. V.) v .Y

48 are forming-dies having arms 49, containing slots V50 and provided with grooves 5,1, thatreceive the tongues 44 of the leverarms 43, whereby a dovetail joint is provided between the levers 42 and forming-dies 48,7so that the dies may be adjusted on said levers. The. dies are held to the levers by screws 5,2 passing through the slots 50 and seated in the lever-arms 43. The inner working surfaces 0f the forming-dies are of any configuration corresponding to that desired to .be formed upon the. exterior of thebottle-neck.

the manner of contact between thedies and bottle-.neck being illustrated in Fig. VI.

Fixed to the shaft 24 forward of .the-rear post 2 2 is acollar 53,` provided with a groove.

5,4, arranged to. receive a yoke`55, these parts being designed for service in accomplishing longitudinal or endwise movement of the Shaft24in the manner to be. hereinafter ex-.-

plained.. rlheforward end'of the shaft 24 is provided with a4 socket adapted to receive a removable forming-tool .'56, by which the interior of the bottle-neck is shaped, this tool being thrust forwardly into the bottle-neck through the sleeve 33 when the bottle is placed `against the end of the sleeve to be formed. t 57 is a gage-collar secured to the forward end-of the sleeve 33, adapted to receive the bottle-neck to confine it while being shaped. In the practical use-of the machine -it is necessary that the shaft 24 beprojected forwardly-to carry the tool 56 into. the bottleneck while the shaft is revolved, whereby the iinterior of the neck is shaped. It is also necessary that the loose collar 38 be shifted on the sleeve A33 to cause the forming-dies 48 to be brought against the exterior of the bottlc-neck, while the toollf56 is projected into the` interior of said nec-k.V In order-toaccomplish the movement of the parts named in the manner stated, I employ means for shifting the shaft and collar that will now be described. l

Located onthe supplemental tablelf?` is a frame 58, having uprights'59, `60, and 63and supported by the vframe 58` are boxes 65. Slidablymounted in the boxes are a front slide 6,6.and a rear slide 6.7. 'Ihe fron-t slide 66 has connected to it theyoke 55,y that engages the grooved collar-53, located on the shaft 2.4,I andit is through movement of this slide that the shaft 24 receives longitudinal movement, las will appear.l The forward endof the rear slid-e 67 has connected to it a yoke 40, that engages in the grooved; collar 38, mounted l011 thesleeve 33, and it is through the movement with, that receives a slide-bolt 71, surrounded @by a spring 72. yThe rear end of the bol-t 71 iis connected to a slide 73, larranged `to operate in the guide-frame 68. rIheslide 73contains a bolt 74.

which is provided witha slot 77, adapted to l receive the bolt 74, so. that said bolt may play therein. The bell-crank 75 is mounted on a Ltrunnion 79, projecting from the upright 59 81 designatesa reciprocatingbar vertically arranged in front of the frame 58.l In the lower end of the oscillatory bar 8,1 is a pivotbolt 87, that receives the connection of one arm of` a bell-.crank 88, pivoted tothe table of the machine,.the bolt 87 being received by ayslot 89 in the bell-crankarm. The oppo- :site end of the bell-.crank 88 haspivoted to it o neend` of; theconnecting-.rod 90, the opposite end of said rod being joined to. a handlever 91pivoted tothe machine-table..iV `Fixed tothe machine-table, besidethe hand-lever, is

75 designates a bell-crank the arrn 76 of "of the frame 5,8, and hasa forwardly-project- Y IOO IIO

IZO

a sector 92, containing apertures 93, adapted to receive a pin 94, by which the throw of the hand-lever may be limited to control the consequent movement of the bar 81, that is moved when the lever is rocked. The bar 81 is provided at the edge facing the bellcrank arm 80 with a lug 82, and lying against the side of the bar 81 is an adjustable stop 83, provided with a slot `84, that receives a bolt 85, inserted through the bar. The space between the lug 82 and a lip projecting from the stop 83 receives the end of the bell-crank arm 80, so that movement imparted to the reci procating bar is communicated to the`bellcrank 75. When it is desired to project the shaft 24 forwardly to carry the tool 56 into the neck of the bottle to be shaped, the handlever 91 is moved inwardly, and the reci procating bar 81 is thereby caused to move downwardly, throwing the arm 80 of the bell-crank 75 downwardly and the arm 76 forwardly. In such vaction the spring 72 serves as a buffer to prevent jar in the initial movement of the slide 66, and as the parts are moved, as described, the guide-frame is carried forwardly, moving therewith the slide 66 and yoke 55. The yoke having engagement with the collar 53 on the shaft 24 causes said shaft to be thrust forwardly to project the tool56 through the forward end of the sleeve 33, the shaft at the same time being turned through Ithe revolving of the bevel-pinion 29.

I next come to the description of the parts by which the die-carrying levers 42 are moved,

these levers being actuated just subsequently i to the forward projection of the tool 56.

95 designates a bolt passing through the vertical slot 61 in the upright 60 of the frame 58, (seeFig. IV,) and seated in the reciproeating bar 81, so that the movement of said barv causes the movement of the bolt 95 in the slot 61.` Pivotally mountedon the bolt 95 is a dog 96, having in its lower end a'cam-slot 97, arranged to play on the stub 62, projecting from the upright 60, so that the dog may be "rocked as it is lowered. The upper end of the dog gis provided with a hook 98, that as the dog is moved downwardly by the bar 81 is brought into engagement with the arm 99 of a bell-crank 100, pivoted to a stub-shaft 101, projecting from the frameupright 58. The arm 102 of the bell-crank 100 contains a slot 103, that receives a bolt 104 in one end of a link 105, the opposite end of said link being connected at 106 to the rear slide 67. As the bar 81 is moved downwardly in the manner before explained the dog 9'ris moved therewith and the hook 98 comes in contact u with the bell-crank arm 99, causing the bellcrank to be rocked to impart movement to the link 105 and project the slide 67 forwardly, 4

thereby moving the yoke 40,and consequently the grooved collar 38 on the sleeve 33. As the collar 38 is moved the rear-arms45 of the levers 42 are spread and the-forming-dies 48 are caused to approach each other and brought against the bottle-neck located on the tool 56 to shape the exterior of said neck, the dies at the same time revolving in an opposite direction to that in which the shaft 24 and tool 56 are turned, as explained.

I will next describe the machine as used in producing a screw-thread on the interior of the bottle-neck in addition to otherwise forming the interior and forming the exterior. The machine as used in suchinstance is illustrated in Figs. VII to X,inclusive. The forming-dies 48a, that operate upon the exterior of the bottle-neck, are actuated similarly to the dies 48,hereinbefore described; but the bevelpinion 29a is loose upon the shaft 24, the

feathering-screws 32a being withdrawn from the groove 26a in said shaft. By this arrangement the pinion 29a turns loosely upon the shaft 24a to communicate movement through the bevel-gear 37a to the bevel-pinion 34a to drive the sleeve 33, its forward end the thread-forming tool 56, adapted for service in producing a screwthread on the interior of the neck of the bottles to be operated upon. In the use of the tool 56fL it is necessary that the shaft 24a have imparted to it a positive forward thrust and simultaneous rotation. To obtain these movements, I apply to the screw 25 at the rear end of the shaft a sleeve 107, having an interior screw-thread corresponding to the screw 25. This sleeve is connected to the screw-threaded neck 28 of the journal-bushing 27. Fixed to the end of the shaft 24 beyond the screw 25 is a pinion 108.

109 designates a rocking shaft mounted in bearings 110 and provided with a handle 111. Carried by this rocking shaft is a toothed segment 112, the teeth of which are adapted to mesh with the teeth of the pinion 108. Upon rocking the shaft 109 the operator rotates the pinion 108, and thereby turns the shaft 24L and screw 25. The screw 25 turns in the sleeve 107, causing the shaft to be thrust forwardly as it is turned, and by this means the screw-forming tool 56% receives the required forward movement and rotation to produce the screw-thread upon the interior of the bottie-neck.

In the use of the machine to produce screwthreads upon the exterior of bottle-necks I alter and arrange the parts into the form shown in Figs. XI to XVI, inclusive. The shaft 241 is equipped with the forming-tool 56, similar to that shown in Figs. I to VI, inclusive, and the bevel-pinion 29b is mounted on the shaft 24b and prevented from turning thereon by the feathering-screws 32", that enter into the groove 2Gb in the shaft. The

bevelpinion 34 is omitted. The forward thrust of the shaft 24b is accomplished by the actuation of the yoke 55b in a similar manner to that described in connection with the shifting of said shaft as shown in Figs. I to VI, and the parts by which said yoke 55b is actuated are indicated upon the drawings by The shaft 24a carries at Y IOO IIO

similar unmet-ais, with the affix renew-b to those designating the same. parts in Figs. I to VI.

48h designates the forming-dies for the;v exterior of the bottle-neck, containing threadgrooves adapted to make. their impressi-'on upon the'bottle-neck to produce threads thereon.. As the bottle-neck is merely compressed betweenthese diesthere is no neces each other upon the rearward movement ofl the sliding collar 38h, riding between the levers 42", and the sl-ide 67by is likewise moved rearwardly instead of forwardly in closing the dies. The connection between the said slide and the reciprocating bar Slbto cause such movement is by a link 114:', connected at onek end to the slide 67", and having its opposite end connected to one arm of a bellcrank 115. The other arm plays in a socket 86, carried by thereciprocating bar 81h'. On referring to Fig. XII ,it will be seen that the bel'lcrank 75, is located upon one s-idefof'said reciprocatingk bar and the ,bell-crank 115i on the opposite side` and that therefore inthe movementof the reciprocating bar said bellcranks are moved at the same time, but vcon- 'trary-.to each other, with the result that the slide 66bis moved forwardly to shift the shaft 2149 and the slide 67b is moved rearwardly to shift the collar 38h rearwardly and close the dieseachtime that the` bottle-neck isshaped.
